Part number description:

the sheath comprises a sheath body 1, an attaching plane 11, a gradually-expanding arc-shaped surface 12 and a sheath opening 2.

Detailed Description

The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.

In the embodiments described below, outside-in refers to the direction from outside the patient's nares to inside the nares.

With reference to fig. 1 to 8, the nasal protective sheath of the present invention comprises a hollow sheath main body 1, wherein the sheath main body 1 is located in the nasal cavity of the patient during the operation, the sheath main body 1 adopts a gradually expanding structure gradually expanding from outside to inside, wherein the sheath main body 1 comprises an attached plane 11 attached to the nasal septum of the patient and a gradually expanding arc-shaped surface 12 attached to the wall of the nasal cavity of the patient. Here, the cavity walls to which the diverging arc-shaped faces 12 are attached are the bottom wall, the outer side wall and the top wall of the nasal cavity.

Before an operation, the sheath main body 1 of the nasal cavity protective sleeve is inserted into the nose, the large end of the sheath main body 1 is inward when the sheath main body is inserted, and the attaching plane 11 faces to the nasal septum of the nasal cavity of a patient when the sheath main body is inserted; during the operation, attached plane 11 is attached on the septum nasi, and the degree of matching of the shape of whole nasal cavity protective sheath and the shape of nasal cavity is high, and the difficult emergence of nasal cavity protective sheath is rotated when receiving apparatus external force, is favorable to improving the protective effect of nasal cavity protective sheath to the nasal cavity mucosa, makes the usable space maximize of nasal cavity.
